Link releases 85K Air Link tandem drive chassis suspension

March 25, 2020  By Link

Sioux Center, Io. – Link announced its 85K Air Link tandem drive chassis suspension is available for select makes and models. Originally designed to meet the demands of the U.S. military, the 85K Air Link has been optimized for heavy vocational commercial applications and was revealed to the industry at CONEXPO/CON-AGG.

The tandem drive chassis suspension is designed with large, high-volume, low-frequency air springs that enable occupants to experience a consistently smooth and comfortable ride whether their vehicle is under load or empty. Dual height-control valves ensure that proper ride height and vehicle levelling are maintained, thus maximizing roll stability regardless of the weight and balance of a vehicle’s cargo.

Link’s air-over-walking-beam technology was patented close to 30 years ago and was originally designed to cope with extreme payloads and harsh off-highway defence applications. The suspension provides a smooth, comfortable, uncompromising ride.

“Link’s 85K Air Link tandem drive chassis suspension has been optimized for select heavy vocational axles and will now deliver Link’s legendary ride quality at the highest capacity for any air spring suspension in North America,” said Neil Mardell, manager defence programs and heavy vocational products for Link.


The system’s ability to equally distribute weight, its high roll stability and its tractive superiority make operating on challenging off-highway terrain safer, more comfortable and ultimately more controlled. Like all Air Link suspensions, the 85K is 100 per cent off-highway rated, designed to not only survive but thrive in punishing off-highway environments, and once wheel alignment is set on an Air Link, no future adjustments are required.

“The Air Link also offers users all the advantages of a combined air spring and walking beam suspension without all the downsides of more primitive steel or rubber walking beam suspensions,” said Mardell.

All Air Link suspensions are treated with Link’s exclusive Link-KOAT migratory self-healing metal treatment. Link-KOAT provides corrosion resistance and rust protection, even when surfaces are exposed to excessive abrasion, harsh chemicals and other severe-duty environmental factors. The 85K Air Link tandem drive chassis suspension includes an extended three-year warranty.

“Our 85K has been engineered to seamlessly interface with tier-one online installation processes,” said Mardell. “The Air Link 85K has served its time in the military and is ready to do super-heavy duty in the commercial sector.”
